The fourth-seeded Sooners (40-19) scored three times after White reached on a catcher's interference call with two outs in the first inning, and Oberste roped his 11th home run into the left-field bleachers in the third to make it 5-1. Oberste tacked on a two-run single in the ninth.

Freshman Jacob Evans (7-2), usually the team's closer, made the lead stand up by limiting Kansas to one run in five innings of relief.

Kansas (34-25), the No. 6 seed, got its only runs on sacrifice flies from Michael Suiter in the first inning and Ka'iana Eldredge in the fifth.
